A tree means life, as it is a lively self-supporting organism with a woody stem. A tree transforms carbon from the atmosphere into sugars, which it uses to generate the cellulose and lignin building components required to sustain its entire living structure. Sugars are created and distributed throughout the tree via its inner bark known as the phloem, to where they are needed. Some of the sugars are stored inside the root systems, the trunk, and branches until needed by the tree.
